Pile Theme crashes wordpress

Dear community,
I bought the Pile theme from pixelgrade years ago and loved it. But now it crashed my whole Wordpress and I have no idea why. I downgraded the wordpress so that is definitly compatible and downloaded the current pile theme again and installed it. But when I do it, first of all nothing looks the same anymore, all my settings are gone and a day later my wordpress crashes again and my website is not longer available. Any suggestions or ideas?
Thank you upfront.


I am not sure but I think it is compatibility issue. If you check the theme details you will find:
Software Version => WordPress 5.1.x
where the current version is 5.6

You can try to get in touch with theme author and ask them when they are planning to update the theme to make compatible with latest wp and plugins.
